Short summary
We studied how invertebrate communities of mudflats are affected by sudden deposition of sediment. We applied sediment layers of different thickness to mudflat communities and studied how their densities, diversity, and behaviour and the exchange of oxygen between the bottom and the water column changed. We found that some species easily diminish in numbers, while others become more active after deposition. The interaction of all species effects influences the environment, i.e. oxygen exchange.
